INTRODUCTION
Congratulations on your purchaseofthe DSC PC1000BurglarAlarm Control System.
This equipment has been designed to give you the greatest possible flexibility and
convenience in the use of your security system. This booklet is intended to serve as
a handy reference and should be kept in a secure place.
Your DSC PC1000 Security System is made up of a control panel, one or more
keypads, and various detectorsand sensors. The control panel will be mounted out
of the way in a utility room or basement. The metal cabinet contains the system
electronics, fuses and stand-by battery. There is normally no reason for anyone but
the installer to have access to the control panel. The keypad(s) have display lights
and command entry keys. The keypad is used to send commandsto the system and
todisplaythe currentsystemstatus. Keypadsare mounted in convenientareas close
to the exit-entry doors. The security system has up to four zones or areas of
protection. Each zone used will have connected to it various sensors, such as door
or window contacts, motion detectors, glassbreak detectors and vibration or shock
sensors. When a sensor is in alarm, a keypad light will be on to indicate which zone
is in alarm. The "Ready" light on the keypad will come ON when all the detectors are
closed. The "Ready" light indicates the system is ready to arm.
IMPORTANT NOTICE
Digital Security Controls Ltd. recommends that you read this manual carefully and
become familiar with the operation of your security system. Check with the installer
to seewhich commands listed in this manual applyto your particularsecurity system.
Fill out the system reference sheet and store this booklet in a secure place for future
reference. It is important to test your system every week. To do this, first inform the
monitoring station that you are testing your system. Then, with the system disarmed,
activateall detection sensors one at a time and observe the zone lightcome on at the
keypad as each sensor is activated. Perform a bell test by using the [*],[4]
command. The PC 1000canbeprogrammed atthe timeofinstallation to automatically
perform a test transmission to the monitoring station on a regular basis. If the system
has not been programmed for this automatic test, call the monitoring station for
instructions on how to perform a test transmission. Don't forget to inform the
monitoring station when you have finished your test.
Check to see if the "System" light is on when arming the system. The "System" light
will be on if a zone is bypassed, an alarm has occurred, or if there is a system trouble
condition. See the Trouble Display section in this manual for a description of the
different trouble conditions. Contact your installer for assistance if the trouble
condition cannot be located and corrected.
IMPORTANT NOTE------------
Rememberthat nosecuritysystemcan preventemergencies. It isonly
intended to alert you in case of an emergency and should not take the
place of prudent security practices or life and property insurance.

smoke detector. Contact your installer for information on safe methods to
activate a smoke detector.
7. Should your system fail to operate properly, call your installer for service.
8. When testing is complete, call and advise the monitoring station.
MAINTENANCE
With normal use, the system requires minimum maintenance. The following should
be observed:
1. Donot wash the keypad with a wet cloth. Light dusting with a barely dampcloth
should remove normal accumulations of dust.
2. The battery/bell test is designed to determine battery condition, however it is
recommended that the stand-by battery be replaced every three years.
3. For other system devicessuch as smoke detectors, passive infrared, ultrasonic
or microwavemotion detectors or glassbreak detectors, consult the respective
manufacturer's literature for testing and maintenance.
FIRE SAFETY IN THE HOME
Most fires occur in the home and to minimize this danger it is recommended that a
household fire safety audit be conducted and a family escape plan be developed.
HOUSEHOLD FIRE SAFETY AUDIT
1. Are all electrical appliances and outlets in a safe condition? Check for frayed
cords, over-loaded lightingcircuits, etc. If you are uncertain aboutthe condition
ofyourelectricalappliancesorhouseholdservice, haveaprofessionalevaluation.
2. Are all flammable liquids stored safely in closed containers in a well ventilated
cool area? Cleaning with flammable liquids should be avoided.
3. Are fire hazardous materials (matches) well out of reach of children?
4. Are furnaces and wood burning appliances properly installed, clean and in
good working order? Have a professional evaluation.
FAMILY ESCAPE PLANNING
There is often very little time between the detection of a fire and the time it becomes
deadly. It is thus very important that a family escape plan be developed and
rehearsed.
1. Every family member should participate in developing the escape plan.
2. Studythe possibleescaperoutes from each location within the house and since
manyfires occurat night, special attention should begiven to the escape routes
from sleeping quarters.
Continued... ►
10
FAMILY ESCAPE PLANNING (Continued)
3. It is essential that escape from a bedroom be possible without opening the
interior door. Consider the following when making your escape plans:
• Make sure that doors and windows that open to the outsideare easily opened.
Ensure that they are are not painted shut, and that their locking mechanisms
operate smoothly.
• If opening the exit or using the exit is too difficult for children, the elderly or
handicapped, plans for rescue should be developed. This includes making
sure that those who are to perform the rescue can promptly hear the fire
warning signal.
• If the exit is above the ground level, an approved fire ladderor rope should be
provided as well as training in its use.
• Exits on the ground level should be kept clear. Be sure to remove snow from
exterior patio doors in winter; outdoor furniture or equipment should not block
exits.
• The family should have a predetermined assembly point where everyone can
be accounted for; for example, across the street or at a neighbour's house.
• Once everyone is out of the house, call the Fire Department.
• A good plan emphasizes quick escape. Do not investigate first or attempt to
fight the fire, and do notattempt to rescue belongings or pets as this takes up
valuable time. Once outside, do not re-enter the house. Wait for the fire
department.
• Write the plan down and rehearse frequently, so that should an emergency
arise, everyone will know what they are to do. Revise the plan as conditions
change; for example, when there are more or fewer family members in the
home, or if there are changes to the house.
• Make sure your fire warning system is operational by conducting weekly tests
as noted elsewhere in this manual. If you are unsure about system operation,
contact your installing dealer.
• It is recommended that you contact your local fire department and request
further information on home fire safety andescape planning. If available, have
your local fire prevention officer conduct an in-house fire safety inspection.
